Gravitational form factors of the proton from near-threshold vector meson photoproduction
Xiao-Yun Wang, Fancong Zeng, Jiyuan Zhang
We embark on a systematical analysis of the quark and gluon gravitational form factors (GFFs) of the proton, by connecting energy-momentum tensor (EMT) and the near-threshold vecto…
Analysis of the contribution of the quantum anomaly energy to the proton mass
Xiao-Yun Wang, Jingxuan Bu, Fancong Zeng
Inspired by the recent Hall C and GlueX measurements of photoproduction, a systematic analysis of the contribution of quantum anomalous energy (QAE) to the proton mass is car…
Near-threshold photoproduction of in two-gluon exchange model
Fancong Zeng, Xiao-Yun Wang, Li Zhang +3
The near-threshold photoproduction of is regarded as one golden process to unveil the nucleon mass structure, pentaquark state involving the charm quarks, and the poorly cons…
Fitting the trajectories of particles in the equatorial plane of a magnetic dipole with epicycloids
Fancong Zeng, Konstantin Kabin, Xiao-Yun Wang +1
In this paper we discuss epicycloid approximation of the trajectories of charged particles in axisymmetric magnetic fields. Epicycloid trajectories are natural in the Guiding Cente…
